The following devices support programmable power up states:
- 651x (6512, 6513, 6514, 6515)
- 652x (6525, 6527, 6528),
- All M Series boards (62xx)
- All X Series boards (63xx)
You can set power-up states in NI Measurement & Automation Explorer
(NI MAX) or with the DAQmx Set Power Up States
(Digital) function/VI. Using NI MAX is the recommended method. The programmable states are :
- Logic low (0 V-0.8 V)
- Logic high (2 V-5 V)
- Tri-state (floating)
You can only specify a programmable power-up state of tri-state
on devices with a configurable direction.Note:
I/O direction on static DIO devices is port-configurable only. Therefore, you can set the power-up state to tri-state only on a port-by-port basis. You can, however, set individual digital output lines in a port to logic low or logic high.
Updating these sets the states to which to set physical channels on a device when the DAQ device powers up or when you reset the device. A device stores power up states in non-volatile memory that you can write to only a limited number of times. The write only occurs if a setting you request is different from the one currently stored. This article details the steps to alter these states in NI MAX and LabVIEW as well as how to read the states from the EEPROM in LabVIEW.
